Product details
Overview
The MAX4541CUA+T from Maxim Integrated is a precision dual single-pole/single-throw (SPST) analog switch with two normally open (NO) channels, designed for low-voltage, single-supply operation from +2.7V to +12V. It delivers 60Ω max on-resistance, 2Ω max RON matching between channels, 5pC max charge injection, and guarantees break-before-make switching only in SPDT variants (not applicable here). It is widely used in battery-powered audio/video routing and +3V/+5V ADC/DAC signal path selection.
For engineers reviewing the MAX4541CUA+T datasheet, MAX4541CUA+T pinout, MAX4541CUA+T application, or MAX4541CUA+T equivalent, key selection criteria include its SOT23-8 package footprint, TTL/CMOS-compatible logic inputs, guaranteed low leakage (<10nA at +85°C), fast switching (tON = 35ns typ, tOFF = 25ns typ at +5V), and compatibility with MAX323/MAX324/MAX325 pinouts.
Technical Context
The MAX4541CUA+T implements a CMOS transmission-gate architecture optimized for bidirectional analog signal routing with rail-to-rail voltage handling (GND to V+). Its control logic accepts TTL/CMOS levels across the full supply range and features internal protection diodes enabling robust operation without external clamping in most designs.
It operates as a dual independent SPST switch - both channels are normally open and activated high - with no internal inter-channel coupling beyond specified crosstalk (-90dB at 1MHz) and off-isolation (-76dB). Charge injection (5pC max) and RON flatness (6Ω max) are tightly controlled to preserve signal integrity in precision sample-and-hold and multiplexing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.7V to +12V single supply - supports direct integration into 3.3V, 5V, and 12V systems without level shifters. |
| On-Resistance (RON) | 60Ω max (33Ω typ) at +5V - ensures minimal signal attenuation and gain error in sensor/ADC front-ends. |
| RON Matching | 2Ω max between channels - enables precise differential signal routing and matched gain paths. |
| Charge Injection | 5pC max - limits voltage glitch on sampled capacitors, critical for 12-bit+ data acquisition accuracy. |
| Leakage Current | 10nA max at +85°C - preserves battery life and prevents DC offset drift in high-impedance sensor interfaces. |
| Switching Speed | tON = 35ns, tOFF = 25ns (typ, +5V) - suitable for audio-band multiplexing and medium-speed digital I/O isolation. |
| ESD Protection | >2000V per Method 3015.7 - provides robust handling during board assembly and field operation. |
Pinout & Package
MAX4541CUA+T is housed in an 8-pin SOT23-8 package (top marking: AAAE for -40°C to +85°C grade; MAX4541CUA+T is 0°C to +70°C grade, unmarked per ordering table). The package measures 2.90mm × 2.90mm × 0.80mm with 0.65mm lead pitch and exposed pad (EP) connected to V+ per TDFN variant - though EP is not present in SOT23-8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | COM1 | Analog common terminal for Channel 1 - bidirectional, supports rail-to-rail signal swing (GND to V+). |
| 2 | IN1 | Digital control input for Channel 1 - TTL/CMOS compatible; high = closed (NO1 connected to COM1). |
| 3 | GND | Ground reference for analog and digital sections - must be low-impedance for leakage and noise control. |
| 4 | NC2 | Not internally connected - left floating; no electrical function or thermal role. |
| 5 | COM2 | Analog common terminal for Channel 2 - electrically isolated from COM1; identical performance specs. |
| 6 | IN2 | Digital control input for Channel 2 - independent of IN1; enables asynchronous channel control. |
| 7 | V+ | Positive supply input - powers analog switch core and logic interface; absolute max = +13V. |
| 8 | NO1 | Normally open terminal for Channel 1 - connects to COM1 when IN1 = high; NC1 is unused in MAX4541. |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance flatness | 6Ω max variation over full analog signal range - maintains consistent gain/attenuation across input voltage. |
| TTL/CMOS logic compatibility | Guaranteed operation with 0.8V/2.4V thresholds at +5V - eliminates need for external level translators. |
| Ultra-low power consumption | <5µW quiescent supply current - extends runtime in coin-cell or energy-harvesting systems. |
| Pin compatibility | Direct replacement for MAX323/MAX324/MAX325 in SOT23-8 layout - reduces redesign effort and BOM consolidation. |
| High off-isolation | -76dB at 1MHz - suppresses crosstalk between active and inactive signal paths in multi-channel systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX323ESA+ | Higher RON (100Ω max), slower switching (tON/tOFF = 120ns/80ns), same SOT23-8 pinout and logic interface. | Less suitable for precision 12-bit+ data acquisition due to higher on-resistance and charge injection (10pC). | Select MAX323ESA+ only if legacy design reuse or cost sensitivity outweighs performance requirements. |
| ADG702BRMZ-REEL7 | Lower RON (3.5Ω typ), wider supply (1.8V–5.5V), but no guaranteed break-before-make and different pinout (MSOP-8). | Preferred for ultra-low-RON applications like RF front-end switching, but requires PCB redesign and lacks 12V tolerance. | Choose ADG702BRMZ-REEL7 when operating below 5.5V and sub-5Ω RON is mandatory; not drop-in compatible. |
Compared with MAX323ESA+, the MAX4541CUA+T offers significantly faster switching and lower RON, improving system bandwidth and accuracy; versus ADG702BRMZ-REEL7, it supports higher supply voltages and maintains pin compatibility with legacy Maxim switches but trades off some on-resistance performance.

FAQ
What is the maximum supply voltage rating for the MAX4541CUA+T?
The MAX4541CUA+T has an absolute maximum supply voltage (V+) of +13V, with recommended operating range from +2.7V to +12V. Exceeding +13V risks permanent damage. Operation at +12V is fully characterized and supported per datasheet Electrical Characteristics tables, delivering optimal RON and leakage performance within specification limits.
Does the MAX4541CUA+T support break-before-make switching?
No, the MAX4541CUA+T does not support break-before-make switching. That feature is explicitly guaranteed only for the MAX4543 and MAX4544 variants (SPDT configurations). The MAX4541CUA+T is a dual SPST device with two independent normally open switches; simultaneous channel activation is permitted and does not cause short-through conditions.
What package type and dimensions does the MAX4541CUA+T use?
The MAX4541CUA+T uses an 8-pin SOT23-8 package measuring 2.90mm × 2.90mm × 0.80mm with 0.65mm lead pitch. It has no exposed pad (unlike TDFN variants), and top marking follows Maxim's standard for commercial-grade parts - though MAX4541CUA+T itself carries no laser marking per ordering table (only AAAE-marked E-grade parts do).
Can the MAX4541CUA+T operate with a +3.3V supply?
Yes, the MAX4541CUA+T is fully specified for +3.3V operation (within the +2.7V to +12V range). At +3.3V, typical on-resistance rises to ~275Ω, tON/tOFF increase to 80ns/50ns, and leakage remains ≤10nA at +85°C. Logic inputs remain compatible with 0.8V/2.4V thresholds, supporting direct connection to 3.3V microcontrollers.
Is the MAX4541CUA+T pin-compatible with the MAX323 series?
Yes, the MAX4541CUA+T is pin-compatible with the MAX323, MAX324, and MAX325 in the SOT23-8 package. Pin functions (COM1, IN1, GND, NC2, COM2, IN2, V+, NO1) match identically, enabling direct substitution without PCB modification - though designers must verify timing, RON, and leakage requirements meet system needs.
